Ok first question: Does anyone have a picture of a gm 10 bolt posi rear end with the cover off? The reason for asking is I'm gonna take off the cover to mine to see if its posi. Pretty sure it is but worn out. If I jack up the rear and rotate the tires they go opposite; however sitting at a stop light and romping on the gas both tires burn with mad tire hop. Damn near twists the car in two even with SFC's and STB. For the second question: if in fact I do have posi and its worn out, is the Zexel-Torsen differential P/N64501T from SLP a posi unit and a good replacement?

Sorry but I tried the search and got back a bunch of crap. Maybe I'm asking the wrong question. Anyways here's the link: http://www.slponline.com/view_produc...TNUMBER=64501T

im very happy with my SLP take off posi. They are taken off of newer LS1 camaros so they should be able to handle 310+HP. you shouldnt have to worry about which axles you have, most 90 and up camaros already have 28 spline axles, i have a 90 RS and mine did.
